I have variegated loriope to plant in places where voles have eaten roots of previous ones. Is there anything I could put on new plants to keep voles from eating them? Would red pepper or a pesticide hurt the new plants?
Repellents are not effective in vole control and no pesticides are recommended as it can pose risks to humans and other wildlife There are no easy answers. Control involves trapping with mouse traps baited with apple slices or peanut butter. Fall is a good time to trap as there are fewer food sources. Reduce their habitat by keeping weeds, increase the spacing between the plants, and make sure mulch is no thicker than an inch and keep away form the base of the plants.
